TEMPORARY BINDER AND LOCK.

SPECZFICATION forming part Of Letters Patent No. 604,561, dated May 24, 1898.

Application filed January 29, 1897. Serial No. 621,199. (No model.)

To all whom it may concern.-

Be it known that I, HARRY E. DADE, a citizen of the United States, residingin the city, county, and State of New York, have invented new and useful Improvements in Binders and Locks Therefor, of which the following is a specification.

This invention relates to binders, but for the most part to locks, especially such as may be used to fasten together the binding pieces or covers of a binder. The lock is herein specifically shown as used in connection with a binder, certain of its features being especially advantageous in this connection; but in its broader aspect it is applicable in many other and different relations, and I do not wish to be understood as limiting the lock in its use to a binder.

One object of the invention is to provide a strong, simple, and efficient lock that is capable of extension, so as to fasten two parts or pieces together securely at different distances apart.

Another object is to so arrange the lock that when the two pieces or parts are fastened together the lock cannot be extended, so as to permit the pieces to move apart, until they are unfastened.

Another object of the invention is to provide a lock of the characterdescribed especially adapted for use with a binder.

Another object is to improve certain fea tures of binders, and more particularly such as are shown in the patent granted March 10, 1896, to Copeland and myself, No. 555,930.

The invention consists of the various features of construction hereinafter set forth.

In the accompanying drawings, forming part of this specification and illustrating embodiments of my invention as applied to binders,like letters of reference designate similar parts.

Figure 1 is a plan view of a binder, parts being broken away, embodying my invention. Fig. 2 is a plan view of the inner end of a sheet of paper adapted for use in the binder shown in Fig. 1. Fig. 3 is a rear end elevation of the binder. Fig. at is a sectional elevation on the line 4 r of Fig. 1. Fig. 5 is a plan View of the locking devices on the line 5 5, Fig. 4. Fig. 6 is a sectional elevation of a single locking-post embodying myinvention.

Referring now to the particular embodiment of the invention shown in the drawings, A and B are the binding-pieces in the form of covers of a binder and having at their rear ends hinged strips A and 13, respectively. The strip B is provided with two fixed extensible posts Z) b, rigidly connected at their upper ends by the piece I).

o c are two removable posts having heads 0 c and arranged to slide in the tubes 0 0 respectively fixed to the strip B.

D is a sheet of paper or other material adapted for use in the binder and having two closed apertures cl and two open apertures d. The binder and sheets as thus described are fully set forth and claimed in my patent above mentioned.

The upper cover A is movably but permanently attached to the strip b by means of a flap or other flexible connection E, secured to the strip 1) and to the cover in front of the strip A, whereby the cover A may be lifted a considerable distance away from the sheets, so that sheets may be conveniently removed or put in place in the binder. This binder is made expansible for the purpose of receiving moresheets from time to time, as occasion may require, and the covers 0r binding-pieces A and B are arranged to be fastened together by means of a lock which is extensible, so as to be capable of fastening the covers or pieces together whatever may be the distance separating them. The lock which I employ for this purpose is an important feature of the present invention and I will now proceed to describe it.

Gr is a post rigidly or otherwise attached in any suitable way to the strip 13 of the piece or cover B and having one or more adjustable locking pieces or heads H. My invention contemplates the adjustment of these lockingheads by any suitable means, but the means shown in the drawings are those preferred,

thereon and carried by the yoke H.

especially when used in a binder. The post G, as shown,is threaded and carries a threaded member G, adapted to rotate on the post, so as to be adjustable thereon as far up as the head 9. The member G has fixed to it so as to rotate therewith a head 9 and carries a yoke H, on which the locking-pieces H are fixed. i

K K are two posts, generally plain and provided with adjustable members K K, sleeved These posts are suitably secured to the piece B, preferably one on each side of the post G, and with their adjustable members K K serve to strengthen the parts and guide the lockingheads H in their movement. As thus described, it will be seen that the locking pieces or heads H are adjustable lengthwise of the post G by means of the threaded member G and yoke H and that the locking heads or pieces H are therefore carried by the post G. The upper cover A has in its strip A a recess a, in which is carried a suitable locking device L, arranged to engage the lockingheads H. The bottom of the recess a is provided with openings a a to receive the locking-heads in order that they may be engaged by the locking device L.

In the best form of the lock it is desirable, and especially in a binder, to provide means to prevent the adjustment of the locking head or heads when they are engaged by the upper cover A or other piece to be fastened. This is provided for in the present embodiment of the invention and as shown in Figs. 4 and 8. As there shown, the bottom of the recess a has an opening a to receive and fit the head 9 so as to prevent its rotation when within the opening, and therefore the rotation of the member G, thus securing the locking-heads against adjustment when locked to the cover A. The head g is shown as shouldered and square in plan view, and the opening a is correspondingly shaped; but of course the head 9 and opening a could be variously formed, so as to prevent the rotation of the member G. If the opening of is of any shape other than circular, it will prevent rotation of the head 9 when the head is correspondingly shaped to fit the opening. My invention, however, includes any means to prevent the adjustment of the locking pieces or heads when they are engaged, whether by preventing at this time the rotation of the member G or otherwise.

Any suitable locking piece or means may be employed with the cover A to engage the locking-heads II; but I have devised and employ in the best form of the invention a sliding piece L, having locking-faces Z Z, adapted to take under the locking-heads H and securely. hold them. The locking piece or bolt L is generally provided with a spring Z, tending to throw it into locking position. I prefer to employ a key to unfasten the bolt L from the heads H, so that only the person having possession ofthe key may control the bolt. For this purpose the bolt L is provided with an opening Z adapted to receive the head of the key and so shaped that the key, after throwing back the bolt against the spring, is able to retain the bolt in this position. XVhen the key is turned back again for the purpose of withdrawing it, the bolt L is carried forward into locking position and is firmly held there by the spring. This looking arrangement is especially advantageous in a binder because, for one reason, after the bolt L is thrown back both hands are free to lift the cover A from the locking-heads.

In Fig. 6 I have shown my extension-lock in the form of a single post. In this case the post F is threaded and has a threaded member F, similar to the post G and member G in Figs. land 8. This member F has rigidly secured to it a locking-head F so that the locking-head rotates therewith. This head, which is shown as the same in form as the heads H in Figs. 4 and 8, hasasquared shoulderf, which is adapted to fit the opening a in the bottom of the recess a, just as the head 9 does. By this means when the head F is locked its adjustment along the post F is prevented. The member F is limit-ed in its upward adjustment by the head f on the post.

In Figs. 9 and 10 is shown another modification of the invention. In this case the two plain posts M M and the threaded postN between them are secured, as before, to the lower cover 0 of a binder. These posts, however, extend up through apertures in the upper cover 0. The adjustable members on the posts and locking-heads are quite similar to those shown in Figs. 4 and 8, except that in Figs. 9 and 10 the posts pass through the locking-heads and the adjustable members are shorter. In these figures the threaded member P on the post N has fixed to it the shouldered head P and carries the yoke R, rigidly connecting and supporting the locking-heads S,which are formed integrally with the members S, sliding on the posts M. This form of the lock might also be changed to a single post by employing only the middle post N and changing the head P into a locking-head, like the head F in Fig. 6, as will be easily understood. The chief function of the threaded posts in all the figures is to adjust the locking heads, and while I consider the threaded post the best means for this purpose my invention contemplates the use of any other suitable means for the purpose. The threaded post and threaded member, with its shouldered head, are also made available to secure the locking-heads against adj ustment when engaged; but other means for this purpose could be employed without departing from my invention.

Many other changes besides those specified could be made without departing from the purview of my invention.
